Title: Three-dimensional image generator
IPC: G06T15/00
Filed: 1989-10-20
Abstract: A three-dimensional image generator generates a random 
signal which it filters in two dimensions generate a 
realistic three-dimensional image of a natural object such 
as ocean waves or clouds. By performing the filtering 
operation repeatedly on overlapping intervals of the random 
signal, related images can be obtained to generate moving 
scenes at real-time rates. Two or more partial image 
generators can be connected in parallel to generate 
different directions of motion, or different parts of a 
complex scene. Within each partial image generator, two or 
more space filters can be connected in parallel to generate 
superimposed patterns, such as small ripples superimposed on 
large waves. This image generator is much faster than 
previous, fractal image generators.

Title: Linear displacement transducers
IPC: G01D5/20
Filed: 1989-02-07
Abstract: A linear displacement transducer comprises a winding (1), a 
magnetic core (6) which is linearly displaceable relatively to the 
winding (1), and a source (13) for energizing the winding (1) with a 
constant RMS alternating current at a frequency sufficiently high for 
the resistive losses in the magnetic core (6) to cause the voltage 
across the winding (1) to vary substantially linearly relative to the 
linear displacement of the magnetic core (6). The frequency may, for 
example, be in the range 10 to 20 kHz, and a temperature sensing 
winding (4) may be associated with the winding (1) to enable the output 
from the transducer to be compensated for temperature changes, or the 
winding (1) may be used in time-division multiplex for this purpose.

IPC: H01R13/625
Filed: 1989-03-13
Abstract: A screw-coupled connector comprises two coupling parts 
which are capable of being secured together by the rotation 
of an internally screw-threaded nut (3) carried on one of 
the parts, in which the said part includes a sleeve (6) 
which is rotatable independently of the nut, the sleeve (6) 
carrying a plunger (8) which is capable of being moved 
axially under spring pressure in order to enter a hole (12) 
on the nut when the sleeve and nut are suitably aligned, the 
said plunger when in the hole serving to drive the nut (3) 
and also press a ball (14) against an inclined plane (17) on 
a friction ring (16). When the parts of the coupling are 
fully secured together, the nut (3) will be moved through a 
small radial distance with respect to the friction ring 
(16), this will displace the ball (14), move the plunger 
(8) from the hole (12) and disengage the drive from the 
sleeve (6) to the nut (3).  
     The sudden free rotation of the sleeve (6) that appears 
upon tightening the coupling is a clear indication that full 
engatement of the parts has been effected.

Title: Multi-channel remote control transmitter
IPC: G07C9/00
Filed: 1989-09-06
Abstract: A multi-channel remote control transmitter for 
control of apparatus such as vehicle security systems, 
garage door openers, and the like has means for selecting 
one of many different channels or codes to be transmitted 
with a minimum number of control switches (34, 36). The 
transmitter includes at least one channel select switch (34) 
and a transmit switch (36). The user actuates the channel 
select switch (34) to select a desired channel, and then 
actuates the transmit switch (36) to actually transmit the 
selected channel code. The transmitter includes an audible 
(or visual) indicator (62) for confirming to the user the 
particular channel selected. The transmitter provides an 
audible "battery low" signal when the battery voltage drops 
below a predetermined level. A non-volatile memory (64) 
stores an M-bit base code with N least significant bits at 
zero. A microprocessor (50) reads the base code from the 
memory (64) and determines a code to be transmitted by a 
transmitter circuit (70) from the base code and a count of 
number of operation of the channel select switch (34).

Title: Force detector using resistance elements
IPC: G01L5/16
Filed: 1990-01-31
Abstract: There is disclosed a force detector for detecting 
forces exerted in axial directions or moments exerted 
about respective axes using the origin (P) as a working 
point in an XYZ three-dimensional coordinate system. On 
the upper surface of the substrate (10), four bridge 
portions (11 to 14) are formed along the positive and 
negative directions of respective coordinate axes, and 
resistance elements (R1 to R24) having a property such 
that an electric resistance varies due to a mechanical 
deformation are arranged on predetermined symmetric 
positions of respective bridge portions. Bridge circuits 
are constructed by these resistance elements, and 
detection of a force is made by bridge voltage produced in 
the bridge circuit. A strain generative body (20) is used 
in order to transmit an external force to the substrate. 
This strain generative body is provided with a first 
flexible portion (23) having a sufficient flexibility with 
respect to the Z-axis direction and a second flexible 
portion (24) having a sufficient flexibility with respect 
to the direction perpendicular to the Z-axis, thus 
permitting detection sensitivities with respect to 
respective axes to be made uniform.

opposite conductivity type of semiconductor material 
to two semiconductor layers (12) outside resonant 
tunneling barriers (14) on each side of the central 
potential well (10), such that electrons in the well

layers (12). An alloyed reach-through contact formed 
of the same conductivity type semiconductor material 
as the central potential well (10) is extending to the 
central potential well (10). The central potential 
well (10) serves as the base of a three terminal 
device in transport applications, and as the light 
responsive portion for electro-optical applications.

in five layers of the most commonly used gallium-­
aluminum-arsenide compounds, an n GaAlAs substrate, 
undoped GaAlAs, p GaAlAs, undoped GaAlAs, and n GaAlAs.
